If that tree is in front of his lie, then yes. I can't tell from the angle. If it's behind his lie, I think it's ok.

"A follow-through after a putt that causes the thrower to make any supporting point contact closer to the hole than the rear edge of the marker disc constitutes a falling putt and is considered a stance violation."

As an aside, I see lots of people balancing on one foot while picking up their marker after a putt and never touching the ground behind the lie with the back foot. As long as the group deems the person to have "full control of balance", this is ok, right?

I think that in this case it doesn't matter whether the tree is in front of or behind his lie since he is using it to keep himself from falling forward. This means that he did not regain balance after the putt (without outside assistance).

But if that outside assistance is behind his lie, I don't see anything in the rules to disallow it. What if he dragged his back foot along the ground behind his lie, or caught a downed tree with his back foot to keep him from falling forward? Or put his off hand on the ground behind his lie to catch himself from falling forward on a kneeling putt?

"Maintaining balance" during the putt isn't actually part of the rule, see 803.04:

The player must demonstrate full control of balance before advancing toward the hole.

And "falling putt" only matters if it is forwards. Also from 803.04:

A follow-through after a putt that causes the thrower to make any supporting point contact closer to the hole than the rear edge of the marker disc constitutes a falling putt and is considered a stance violation.

Question - "I have a good rules question for you involving the stance rules. A player uses an object (in this case a branch) behind him to maintain balance for a putt. First, would this be considered "full control of balance"? Second, could you argue, if the branch is not so large that the players body weight will not move it, that it is a violation of 803.03 D and or 803.04 A because they could have moved the branch less by not hanging on it? Thanks for any input."

Response - The question can be boiled down to: Can a player hold on to an object behind his lie to maintain balance while throwing/putting?Applicable rules: 803.04 (Stance), 803.05 (Obstacles and Relief), 804.05 (Disqualification and Suspension)

Discussion - The rules do not require that you maintain your balance while putting. You can have a grand mal seizure as long as you don't step ahead of your lie. At the time you decide to step ahead of your lie is when you have to demonstrate balance. This is simply to prove that you are not committing a falling putt, such that you would not be able to stop yourself from falling forward due to the motion of your putt. Grabbing a branch is merely acquiring another support point, which is perfectly legal, as long as it is not ahead of your lie.Holding on to something BEHIND your lie is not prohibited by the rules, provided that the tree that the golfer is using as a supporting point is in-bounds (803.03.A (3)). The branch must not be moved, or else the player would be in violation of one or both of 803.04.D and 803.05.A, which require you to take the stance that results in the least movement of objects that are part of the course and which prohibit you from moving a branch to "make room for a throwing motion".

Conclusion - A player can hold on to something behind her lie, in certain circumstances, without violating the PDGA rules. In general that which is not prohibited by the PDGA rules is allowed, provided of course, that the action done by the player is not considered "a willful attempt to circumvent the rules of play". (This, of course, is cheating!)Other Comments - Many members of the committee have actually tried to hold on to some object behind their lie, while leaning forward to throw or putt. In our opinion this action makes the ensuing throw/putt MORE difficult to accomplish.
